Description

Expected behavior: GUI is running without crashing
Actual behavior: GUI crashes after a random amount of time
Steps to reproduce

(gdb) r /path/to/exec/ign gazebo -g -v 4
(gdb) /path/to/exec/ign -s -v 4 -r shapes.sdf
Wait

Output

See backtrace above in details (Qt::mightBeRichText(QString const&) () at /lib/x86_64-linux-gnu/libQt5Gui.so.5 ??) and ogre2.log

I am having a similar issue where Ignition dies after a few minutes when running ign gazebo with nothing added to the world and get this message.

SEGV received in SEGV handler
/usr/lib/ruby/ignition/cmdgazebo5.rb:438: [BUG] Segmentation fault at 0x0000000000000000
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]

-- Control frame information -----------------------------------------------

If I am running my robot in simulation it also dies after a few min but prints out this log. seg_fault.log

Ubuntu 20.04 with Edifice binary install Graphics card: GeForce GTX 1060 Mobile running nvidia-driver-460 I have a fellow engineer that is experiencing the same issues but he is running in a Docker container.

If this is not related please let me know and I will create a new issue.

@MarqRazz , your backtrace looks similar to the one in #722, pointing to Qt::mightBeRichText

gazebosim / gz-sim
